Ligand Definition. A ligand is an atom, ion, or molecule that donates or shares one or more of its electrons through a covalent bond with a central atom or ion. It is a complexing group in coordination chemistry that stabilizes the central atom and determines it reactivity.
In coordination chemistry, a ligand (/lÉªÉ¡Énd/) is an ion or molecule (functional group) that binds to a central metal atom to form a coordination complex.The bonding between metal and ligand generally involves formal donation of one or more of the ligand's electron pairs.n general, ligands are viewed as electron donors and the metals as electron acceptors. This is because the ligand and central metal are bonded to one another, and the ligand is providing both electrons to the bond instead of the metal and ligand each providing one electron.
